I don't have canvas spectators, but for white canvas plimsolls, I spray them with a 50/50 mix of water and lemon juice and gently scrubbed them for a bit with a stiff toothbrush. Once they're dry, they're a bit brighter. For tougher stains, I mix a tablespoon of baking soda with a touch of water and rub the sticky paste onto the stain (again, with a toothbrush). Let the paste sit for a bit, then brush it off, and usually a bit more of the stain will go away.

I'm hesitant to really recommend this with your Malverns, however. It might be good to try it out on a cheap pair of white plimsolls, or some canvas shoe you don't care about, and see how they fare. After that, try it on an inconspicuous place on the Malverns. I do it without hesitation to my canvas shoes because they only cost something like $50.

I was in Barcelona two weeks ago and the sales associate at Bel Y Cia made a point of noting that they stocked all of their EG models in F width. And they had some nice stuff - not sure about prices but would assume its fairly standard for EG.

Just back from Barcelona.

The price is 700 and something (730 for the model I looked at; obviously, exact price depends on the model) euros.

The shoes are stampled with "Edward Green for Bel y Cia" -- I guess some models are availale only there. And yes, they are in F width, as opposed to standard E.

My shoe size is US 10.5 EE, and tried an EG Inverness UK 10.5 E, it was extremely tight. I don't think the UK 11E will work, the tightness and lacing gap would indicate as much. The best guess would be to go for a UK 11.5 E, and that would be unacceptable for me length wise. I am thinking an UK 11 F would fit the bill, so i might have to end up ordering this from Nick A.

On a side note, the brilliant antique burgundy in all the pics i have seen did not translate in the pair i saw. It was more brown that anything, anyone else experience this?

Lastly, how does the 202 last compare to the 888 last? does it feel like an F width in comparison? Thanks, for the help.

The 202 is roomier than the 888, and significantly wider in the forefoot.

Sorry for being purposefully vague. It depends on your foot shape. I often size up or down depending on last but I have a narrow heel and a wide forefoot. On the 888 I wear 8.5/9F and a 8.5/9E on the 202 if that helps.
